Measurements

Canada Warblers are steely blue-gray above and bright yellow below with an obvious whitish eyering. The most noticeable feature is the broken black necklace across the chest on adult males. Females also have a necklace, but it's not as bold.

Found in mixed conifer and deciduous forests with a shrubby understory. It frequents forest slopes filled with rhododendrons in the southern Appalachian Mountains, aspen and poplar forests in Canada, and forested wetlands in the central part of its range.
